When it ships & how it's delivered · freight to your door

Paragon builds most kilns to order once your order is placed. We email your confirmed ship date and tracking.

  • The freight carrier calls you to book a delivery window.
  • Delivery is curbside with a liftgate. Have a helper or hand truck to move it inside.
  • Check the crate before you sign. Note any damage on the receipt and send us photos.

Authorized Paragon dealer · full factory warranty

Brand new and shipped direct from Paragon, so it carries Paragon's full factory warranty. If something goes wrong, call us and we handle the claim with the factory for you.

Warranty terms are in the Warranty and support section below.

Returns: request within 15 days, unused

Because kilns are heavy and often built to order, returns are limited, so we'd rather help you pick the right one up front:

  • Ask within 15 days of purchase or 2 days after delivery, whichever comes first. We issue a return authorization (RA).
  • It must be new, unused (beyond the factory test fire) and in its original packaging.
  • A restocking fee of at least 25% applies, up to 50% on custom, 3-phase or made-to-order units. Return freight is on the buyer unless we made an error.
  • Damaged in transit? Note it on the delivery receipt, send us photos and we'll help with the freight claim.

Will it work in my space? Power check

Not included: Paragon Knifemaking Heat Treating Kit (gloves, tongs, blade holders, firebrick supports) and gas inlet/flowmeter, both optional upgrades. Requires 240V. Call us to confirm the plug type for your shop before ordering.

Most 240V kilns need their own circuit and the matching outlet, installed by an electrician. Homes are usually 240V; schools and commercial buildings are often 208V, so pick the voltage that matches your panel.

Send us a photo of your breaker panel or outlet and we'll confirm before your kiln is built: 470-264-3563 (call or text).

Overview

Paragon · Heat Treating Oven · Double Barrel Knife Oven Paragon Knife Oven - Double Barrel KM18 Pro KM18 Pro · 240V · 18" chamber length · One extra-wide chamber · 2350°F max Professional double-barrel heat treating oven engineered for high-volume knife making with one extra-wide 18-inch chamber and 3-zone control for large batches. Advanced ceramic fiber construction reaches 500°F in minutes, dramatically reducing cycle time between heat treatments. Fires to 2350°F for hardening, tempering, and annealing all steels including stainless, tool steels, and Damascus.

Heating speed500°F in minutes
What’s included
The oven, assembled and wiredParagon builds and wires it at the factory. The door style you chose is already fitted: a spring-assisted drop door or a side-swing door, both standard at the same price.
Digital controller, factory-installedParagon fits and wires the controller before the kiln leaves the factory. Paragon has been renaming and replacing its controller line and dealer listings are out of date at different dates, so we do not print a model name here. We confirm the exact controller with Paragon when you order.
Type-K thermocouple, installedFitted at the factory and wired to the controller. Type-K is standard across the current Paragon range.
Door safety switchWired in at the factory. It cuts power to the elements the moment you open the door, so you are not reaching into a live chamber.
Cord and plugParagon ships this kiln with a cord and plug. The receptacle type changes with the voltage option you order, so we confirm the exact plug — or whether your configuration is wired direct instead — with Paragon before the order goes in.
Printed manualsA printed instruction manual for the kiln and a separate guide for the controller. Warranty registration is done online at Paragon, and we do not promise a printed warranty card in the crate because we could not confirm one is packed.
Paragon limited warranty — one yearOne year from purchase on this model, per Paragon's published warranty schedule. Paragon does not warrant the Type-K thermocouple, so treat that as a wear part. Keep your proof of purchase.
Not includedNo shelves, posts or kiln furniture ship with a knife oven. The Knifemaker's Heat Treating Kit — four knife holders, eight firebrick supports, a heat treating fork and hot gloves — is a separate purchase, and so are the upgraded touchscreen controller and the gas-inlet option.

Common questions
What types of steel can I heat treat in the KM18 Pro?
The KM18 Pro reaches 2350°F, making it suitable for virtually all knife steels including high-carbon steels (1095, 1084, 5160), stainless steels (440C, AEB-L, CPM-154), tool steels (D2, A2, O1), and Damascus composites. This temperature range covers the hardening requirements for both simple carbon steels and complex stainless alloys. The extra-wide chamber lets you harden more blades per load for efficient workflow.
Do I need a gas inlet port for atmosphere control?
For most knife heat treating, the standard oven without atmosphere control is sufficient. However, if you're working with reactive stainless steels that require scale-free finishes or need to prevent decarburization on high-carbon blades, you can add an optional gas inlet port for argon or nitrogen atmosphere. Many knife makers achieve excellent results without atmosphere control by using anti-scale compounds or foil wrapping.
What controller comes standard and how does it work?
The KM18 Pro Double Barrel includes one Sentinel touchscreen controller that lets you set precise target temperatures and hold times. It uses three thermocouples to control three heating zones, so the temperature stays even along the full chamber length. The rapid heating ceramic fiber construction means you reach set temperatures quickly, reducing wait time between cycles.
How does the KM18 Pro compare to single-chamber knife ovens?
The Double Barrel has one chamber that is much wider than the standard KM18 Pro, so you can load more blades per cycle. Everything in a load runs the same program. The 18-inch chamber length accommodates full-size blades and swords, while 3-zone control keeps heating even across the larger chamber. For professional knife makers or serious hobbyists, the KM18 Pro eliminates production bottlenecks.
Why do I need to buy from an authorized Paragon dealer?
Paragon's one-year warranty is only valid when purchased through authorized dealers like Peach State Pottery, and the warranty must be registered within 30 days of delivery. Authorized dealers provide proper technical support, installation guidance, and access to factory-trained service. Purchasing from unauthorized sources voids your warranty and leaves you without manufacturer support for this specialized heat treating equipment.
